ABSTRACT:
A tunable circuit is disclosed which allows tuning while maintaining a constant Q. The filter uses a synthetic inductor and a capacitance multiplier in place of discrete inductive and capacitive elements. By coupling the synthetic inductor and capacitance through a variable resistor, means are provided for varying the peaking frequency of the circuit while maintaining a constant Q.
